Description
Technical field
The present invention relates to river and lake water quality purifies and the restoration of the ecosystem field; Relate to the device that a kind of lifting plant sinker and floating block three-dimensional coupling purify water; Be particularly related to a kind of can the variation with change of level and regulate sinker and the position of floating block in water body according to water transparency; Reaching the effect of three-dimensional coupling purifying water body, and can be hydrobiont habitat is provided, help the healthy device of aquatic ecosystem.
Background technology
China's present river lake water pollution problem is serious, and numerous lakes present eutrophication, and aquatic ecosystem is constantly degenerated, and the self-purification capacity of water body constantly weakens.How improving the self-purification capacity in lake water territory, river, improve the river lake water environment that worsens day by day, repair and degenerate or impaired aquatic ecosystem, is the subject matter in the present water environment protection.
The river Lake Water Body that adopts in the world at present purifies with ecological reestablishment and mainly contains three types: the one, and physical method; Promptly through engineering measure; Carry out machinery and remove algae, dredge bed mud, diversion dilution etc., but often cure the symptoms, not the disease, can only be as the emergency schedule that tackles sudden water pollution.The 2nd, chemical process, kill algae as adding chemical agent, add molysite promote phosphorus deposition, add lime denitrogenation etc., but cost is big, and is prone to cause secondary pollution.The 3rd, biological---ecological method, as put control algae type biology, structure artificial swamp and aquatic vegetation in a suitable place to breed, this is current research focus.
Biological floating bed technology is to use aquatic ecosystem recovery technology comparatively widely at present.The biological floating bed board-like floating bed of foam, bamboo floating bed, the floating bed of cofferdam type of mainly containing of the waterplant that adopt in lake, existing river.The board-like floating bed cultivated area of foam is big, and the cost cost is lower; But physicals is poor, and very easily damaged, layout is stiff, is confined to large-scale river course, does not have shunt conduit, and can produce the situation of blocking water flood season, and foam belongs to the material of the easy generation secondary pollution that environmental administration lists.Bamboo floating bed is drawn materials easily, and the cost cost is lower; But the bed body is prone to suction from great, and is perishable, is prone to flood season block water, and the view layout is stiff.Cofferdam type plant washability is strong; But cost is high, and no water level regulatory function ties up the river course, and flood passage has obstacle, and this method utilization is less.
Ecological mattress technology is to utilize the mattress carrier and plant the living matrix submerged plant of planting and polluted-water is carried out original position purify and a kind of " biological-ecological " technology of repairing.It is to repair to degenerate or the key of impaired aquatic ecosystem that submerged vegetation recovers, and transparency and illumination condition then are the keys of submerged plant recovery under water.Submerged plant is only survived obtaining just carrying out photosynthesis under the sufficient illumination condition, i.e. the growth of submerged plant must be arranged on the light compensation point or light level of compensation of water body.Intensity of illumination when the net production of plant was zero when light compensation point was meant photosynthesis of plant and respiration balance, the light level of compensation then is the water depth that intensity of illumination equals the plant light compensation point.Yet; In polluted-water; Because a large amount of suspended matters and organic substance have increased absorption and the scattering of light in water body, lower floor's water body intensity of illumination is significantly less than the light compensation point of submerged plant in causing, and submerged plant photosynthesis is less than respiration; Its existence is suppressed and finally causes the extinction of plant community, and the reparation of under this envrionment conditions, carrying out submerged plant is very difficult.Therefore; Submerged plant growth in the polluted-water and the reparation of submerged vegetation are the difficult point problems during water ecology is repaired; Also do not have at present the problems such as illumination condition under water that face in the submerged vegetation rejuvenation in the highly effective technological contaminated solution water body, this also is the main difficult technical that faces in the ecological mattress technical application.
